Funny!
But seriously, I'm not asking for a replacement, but for an
alternative. In the spirit of TIMTOWTDI.
As others said before, logical operators as symbols work nicely when
part of expression, but look (subjectively) better as words when they
are part of flow control. Instead of
bar() if foo();
some may prefer
foo() and bar();
to put emphasis on the fact that foo() is called before bar(). You may
argue that
foo() && bar();
is easier to read. Me, I wonder if this expression should have been
assigned to something, and if there is a bug lurking.
For the same reason I would prefer
foo() dor bar();
to
foo() // bar();
or
bar() if defined foo();
Admittedly, this may be just personal style and preferences, but that
is (part of) why we like Perl over more prescriptive languages.
Cheers,
-Jan
PS: I prefer "dor" over "err" because it uses the same mnemonic trick
as "xor". And my bikeshed is green with pink polka dots.
